BPBAYING DEVICE.

Application med June 12, 1925, Serial No. 36,577. Renewed Iarch .14, 1827.

This invention relates to plumbing de-` vices, but more particularly to automatic sprinklers for spraying lawns, shrubbery and the like. A i

Objects of'tlie invention are to provide a new 'and improved spray head having adjustable features for directing the spray in any predetermined direction; to provide in conjunction with a spray head a replaceable member for directing ythe spray in a definite predetermined direction; and to provide a sprinkling device having the'new and improved features of construction, arrange-` ment and operation hereinafter described.

A further object is to provide a spray head having new and improved features of construction for directing a stream of liquid in a defined path.

Illustrative embodiments of the invention axial bore 15 of the head. An axially elonare shown in the accompanying drawings, in

Figure 1 is a transverse sect-ion on the line 1--1 of Fig. 2; Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1;. Fig. 3 is a vertical section of the device in operative position; Fig. 4 is a front elevation of the.

spray head; Fig. 5 is a section on the line 5-5 ofFig. 2; Fig. 6 is a front elevation of the spray head equipped with a spray vdirecting member for directing the spray to one side only of the device; Fig. 7 shows a spray head having a modified form of spray i directing member for providing a semi-circular sheet of spray; and Figs. 8, 9 and 10 are perspective views of different forms of spray direction members.

The illustrative embodiment of the invention comprises a tubular conduit 1,` which ma communicate with any suitable source of iquid supply, and integral therewith is an enlarged socketv portion 2 vhaving a flanged outer endf3. In the usual manner ofr sprinkling, the conduit and socket portion 2 may be placed in the ground with the flange 3 substantially Hush with the surfacey thereof, so that when not in use the device is not noticeable and does notinterfere with mowing of the lawn.

Between the socket portion 2 and conduit 1 is a partition 4 having a passage 5, and slidable in the passage 5 is a hollow stem 6 on which is formed at the lower end thereof an enlarged head 7 having a bevel portion 8 which is adapted to cooperate with a bevel seat 9 on the partition 4 for providing a iiuid seal between the head and partition when the stem is extended.

Connected to the outer end of the stein 6 circumferentially from each other.v F'orpre` venting rotation of the sleeve 10 a rib 13 is formed in the bore of the socket member 2 and extends axially thereof, this rib projecting into one of the grooves 12.

Connected to the sleeve 10 is a cvlindricall spray .head 14 having in its lower portion a hollow bore 15, which communicates with the bore of the stem 6, and communicating with the bore 15 is a recess or socket 16. The socket 16 consists of afcut-out portion which extends entirely across the spray head 14 and inwardly to the'innerl edge of the gated recess 17 is opposed to the socket 16, and provided on the upper and lower edges of the recess 17 are grooves 18 'which are adapted to fit over the rib 13. It will be apparent that after the spray head 14 has been tightly screwed on the sleeve 10. one of the grooves 12 in the flange 11 of the sleeve may be brought into registration with ,the grooves 18 of the'spray head, thus pre- 85 venting relative rotation of the parts although permitting sliding movement. The outer end of the spray head, is closed by an integral cap 19 which projects radially from the body of the head, and when the device is not in operation this cap rests against a shouldery 2O on the socket member 2 with the outer surface of the flange 13.

For directing the liquid forced through the axial bore 15 in the form of spray, a removable member 21 is disposed in the socket `16 and is held in place by a screw 22 which projects through an elongated opening 23 into threaded engagement with the memberl 21, the head of the screw being disposed within the recess 17. The spray directing member 21, as indicated in Fig. 8, may be semicircular in form, having a fiat surface 24 which is adapted to abut against a portion of the head 14. p v

As shown, portions 25 may be cut out from the inner face of the member with the upper edges inclined upwardly, so that when connected to the s ray head 14, as shown .in Fig. 4, the liquid will be forced in fine streams in opposite `directions at approximately ri ht angles to the axis of the spray head, an is useful for narrow strips of grass. If it is desired', however, to have a semi-circular sheet of spray, the member 21 may be reversed and the tapered circular surface 26 may then be disposed in close juxtaposition to the bore 15, this form bemg used along walks and driveways for sprinkling the grass but keeping the walks dry. 4

It is apparent that when the spray directing member is in the position shown in Fig. 7 with the apex of the semicircular surface in register with the axial passage 15, the wall of spray head 16 adjacent and at right angles to the passagel cooperates with the semi-circular tapering surface and flat parts of the connecting wall 17 on opposite sides of the tapering surface to defiect the stream of water or other liquid from the passage in a defined path.

In the modified form` of spray directing member, the cut-out portions may be dispensed with, as shown in Figs. 7 and 9, and the member 21EL may be used simply for providing a semi-circular sheet of spray. Under some conditions it may be desirable to direct a stream merely to one side of the head, as for use at intersections of walks and driveways, and, as indicated in Fig. 10, the member 211J may be formed with a single cut-out portion 25a, it being understood that this manner is likewise reversible to direct the'spray to the front as well as both sides.

In the o eration of the device it will be apparent t at the liquid entering the conduit 1 will act against the enlarged head 7, as well as against the spray directing member, and move the spray head 14 outwardly from the socket member 2, as shown in Fig. 3, and when the flow of liquid is turned off, the spray head 14 will automatically drop back into normal position within the socket member. Owing to the upright position of the parts, the water within the conduit returns to the supply line, thereby eliminating any danger of freezing in cold weather.

lVhile I have shown and described a construction which is the best form known to me at the present time, it is to bel understood that numerous changes in details of construction,.arrangement and operation may be effected without departing from the spirit of the invention, especially as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a sprayhead having a water discharge passage, a pair of spaced substantially parallel walls on the head at the end of the passage and at substantially right angles to said passage, a wall connecting said pair of walls and disposed at substantially right angles thereto, a reversible spray member having a face formed to seat against either of said pair of walls and having a second face formed to seat against the connecting wall in either position of the spray member,and means ex tending through the connecting wall and into the spray member for connecting the spray member thereto, said spray member having spray-forming faces of differing configuration presented to the stream issu- 'ing from said passage in the said two positions of mounting thereof.

2. A spray head according to claim 1,

wherein one of said faces of the spray member comprises a substantlally semicircular Vtapering water-engaging wall.

3. A spray head according to claim 1, wherein said second face of the spray member is formed with a cut-out forming a downwardly tapering wall which in its operative position confronts the water passage to form a water channel between said cutout and the connecting wall.

4. A spray head having an axial water discharge passage, a wall providing a water deflecting face disposed at right angles to the passage, a second wall extending; outwardly from the first wall and at right angles thereto and located to one side of the Water passage, and a water'defiecting mem-v ber extending outwardly from the second wall and having a substantially semi-circu lar tapering front surface with its apex in substantial register with the water passage, the portions of the second wall beyond the said member also affording water deflecting faces, whereby the two walls and the member all cooperate to direct the water.

In testimony whereof I have hereunto signed my name to this specification.
